Difference between msysgit and Cygwin + git?

What is the difference between msysgit and Cygwin + git?

Now I'm using msysgit, but I don't like the Git Bash (you can't resize or copy/paste) so I'm thinking think about switching to Cygwin, because then I could use mintty.

Edit (2 more years later: October 2014)

Johannes Schindelin just explained (Oct. 2014) that msysgit is phased out:

We now have a light-weight Git for Windows SDK – which is essentially a standard MinGW/MSys system managed through the package manager mingw-get.

We decided to just phase out the name "msysGit" (as well as the GitHub org of the same name) and:

  • work on Git for Windows (with the corresponding GitHub org),
  • using the name "Git for Windows" for the installer aimed at "end-users" and
  • using the name "Git for Windows SDK" for the development environment targeting Git for Windows developers).

Update 2 years later: July 2012

Msysgit is here to stay, and unless you need to add a few hundreds of MB for cygwin, you really don't need Cygwin to just use Git on Windows.
And if you want to access GitHub, you get one package ("Git for Windows" + ssh keys registered for you on your GitHub account + a nice GUI) with GitHub for windows.

Both Git and msysgit are on GitHub.
The msysgit.github.com page clearly illustrates the difference between:

Git for Windows logo <----------> MsysGit logo
"Git for Windows": Pure users of Git | "MsysGit": for Testers, developers, custom installer maintainers

See also the msysgit FAQ:

What is this "MSys" thing in "MSysGit"?

MSys is an environment for Windows offering a Unix-type shell and a Perl interpreter. Because many parts of Git are still not builtins programmed in C, but instead shell and Perl scripts, Git for Windows needs such an environment.

Therefore we ship Git for Windows with a very minimal version of MSys.

MSys is also required to build Git, as we re-use the same Unix-type setup upstream Git uses. We ship a more complete MSys environment, including GCC, as build environment (which is therefore nick-named ''msysGit'').

We compile Git as a pure MinGW program, though, i.e. a program without any link-dependencies on anything but standard Windows libraries.
So unless you need to use any parts of Git that are still implemented only as shell or Perl scripts, you can get away with running plain git.exe.

Original answer: June 2010

a/ You can resize and copy-paste in Git bash, like in any other Windows Shell.

b/ You are probably using "Git for windows", and not msysgit. From the wiki:

  • msysGit is the development environment to compile Git for Windows. It is complete, in the sense that you just need to install msysGit, and then you can build Git. Without installing any 3rd-party software.
  • Git for Windows is an installer which installs Git -- and only Git.

It is easy to see the difference:

  • the installers for Git have the prefix Git-,
  • the msysGit installers have the prefix msysGit-.

Another telltale is that the msysGit installers come in two flavors: fullinstall and netinstall.
Further, msysGit does not install to C:\Program Files by default.
But msysGit comes with gcc, the GNU C Compiler.

c/ From MSysGitHerald10:


  • MinGW is really a very thin compile-time layer over the Microsoft Runtime; MinGW programs are therefore real Windows programs, with no concept of Unix-style paths or POSIX niceties such as a fork() call.
  • MSys, in contrast, is a slimmed-down version of Cygwin (an old version at that), whose only purpose is to provide enough of a POSIX layer to run a bash.

And that is not always welcomed:

When working on Windows, I dislike that msysGit, as the name suggests, depends on MSYS and on tools from the Unix world. I believe all programs in the Git distribution should become binaries compiled for a specific platform, and not rely on shell interpreters or third-party languages like Tcl/Tk.

Even though, it is far better than the first Git on Cygwin installations from 2007.
